How to Survive a Business Tax Audit

Navigate IRS business audits with organized records, calculated responses, and professional representation when stakes exceed $25K.

1. Read the audit notice completely. Identify the audit type: correspondence (mail-only), office (you visit IRS), or field (they visit you). Note the specific tax years, issues, and deadlines. Correspondence audits target 1-3 line items. Office and field audits examine broader patterns and typically signal higher potential adjustments.
2. Gather only the requested documentation. Pull records for the specific items mentioned in the notice. Don't volunteer additional information or years not under examination. Organize by tax year, then by issue. Make copies — never send originals. Bank statements, receipts, invoices, contracts, and depreciation schedules are standard requests.
3. Calculate your maximum exposure. Estimate additional taxes, penalties, and interest if the IRS disallows everything they're questioning. Use 20% accuracy penalty plus 0.5% monthly failure-to-pay penalty as baseline. If your exposure exceeds $25,000, hire a tax attorney or CPA immediately. Below $10,000, handle correspondence audits yourself.
4. Respond within deadlines with documentation only. Submit requested records with a brief cover letter. Don't explain, justify, or provide narrative unless specifically asked. Stick to the examination scope. If you can't locate a document, state that clearly rather than substituting something else. Missing documentation doesn't automatically mean disallowed deductions.
5. Negotiate or appeal unfavorable findings. Review the examination report for errors in law or fact. If adjustments seem reasonable, negotiate payment terms to minimize penalties. If you disagree, request Appeals Office review before the case closes. Appeals settles 85% of cases without Tax Court. You have 30 days to respond to most examination reports.
6. Implement systems to prevent future audits. Document business expenses contemporaneously with receipts and business purpose notes. Maintain consistent accounting methods year-over-year. Avoid round numbers on returns. Keep business and personal expenses clearly separated. File extensions if needed rather than rushing returns with errors.
